The object of the invention is to provide a construction for lifeboats, speed boats, pleasure boats, or rafts in which buoyant members which are designed to be in the form of tubes, are effectively braced transversely and united by transverse assembling means which effectively secure them together; to provide a construction in a device of this kind in which the platform is supported from the transverse assembling members; to provide a construction in which the platform is equipped with a longitudinally extending seat for the accommodation of the occupants; and to provide a construction which is generally of simple character, so as to be susceptible of cheap manufacture and low marketing cost.

lVith this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawings, wherein:

Figure 1 .is a plan view of the invention.

Figures 2 and 3 are respectively longitudinal and transverse sectional views on the planes indicated by the lines 22 and 3-3 respectively of Figure 1.

Figure at is an enlarged detail sectional view showing the connections between adjacent buoyant members.

The buoyant members 10 are of tubular form, preferably cylindrical, and of any desired length to suit the size of boat to be constructed. They are made preferably of galvanized sheet metal rolled to form and seamed, either by welding, riveting, or any acceptable method of construction.

The buoyant members are formed with upwardly tapering extremities as indicated at Diametrical braces 12 extend through the buoyant members and are preferably gal vanized iron pipe which are soldered, welded or otherwise secured to the walls of the buoyant members. Each buoyant member is provided with a plurality of these transverse brace members spaced uniformly therealong and the several buoyant members comprised in any one boat are arranged Serial No. 382,969.

side by side,so that the tubular brace mem bers in each are in axial alignment for the reception of the assembling rods 14, there being an assembling rod extending through all of' the brace members in alignment. Nuts 15 are connected with the tubular brace members where they pass through the walls of thebuoyant members and, at the points of location of the nuts, the buoyant members are depressed as indicated at 16 to provide clea ance spaces for the nuts which are soldered, welded, brazed or otherwise secured to the bolt members. The nuts not only act as spacers between adjacent buoyant members to keep the latter out of side contact that would result in wear of the contacting walls surfaces, but also act, in conjunction with the tubular brace members, to prevent the buoyant members from expanding by the application of weight or pressure in the top thereof. All wear resulting as a result of relative movement between adjacent' buoyant members fallsoii the nuts. The nuts and their connected tubular brace members serve to relieve the buoyant members from any compressive strainthat would be put upon them by tightening the assembling rods.

The terminal nuts of the assembling rods serve to secure to the assembled buoyant members the angles 18 which extend upwardly with their horizontal arms in position to receive the longitudinal runners 19 which are preferably white oak timbers. Bolts 20 extend through the timbers and through the horizontal arms of the angles and secure the runners to the latter, lag screws, as indicated at 20. servin as the attaching means for the rail standards 21 which are spaced uniformly along the platform 22 consisting of transverse timbers spanning the runners 19 and secured thereto.

Guard rails 23 span the rail standards 21 011 either side.

Disposed centrally of the platform and extending longitudinally therealong is a watertight locker 24 having a hingedly mounted top 25 which constitutes a seat for the occupants.

ture.

Piller blocks 28 are mounted on the platform at the bow and stern ends and are provided with oar locks 29 for the use of the oarsmen.

The closing of the ends of the buoyant members in the upwardly tapering form shown makes it possible for them to eifectively deflect any object that would strike them on the end.

By having the construction comprise a plurality of buoyant members, the damage to one or more that would permit them filling with Water will still leave the remainder to support the boat.

The invention having been described what is claimed as new and useful is:

1. A boat comprising parallel tubular members, transverse assembling rods extending diametrically through the tubular members, a platform, and means carried by the assembling rods at their extremities and supporting said platform, the buoyant members being provided with diametrical tubular braces through which the assembling rods extend, the tubular brace members carrying terminal nuts exterior to the buoyant members and serving as spacers therebetween.

2. A boat comprising parallel tubular members, transverse assembling rods extending diametrically through the tubular members, a platform, and means carried by the assembling rods at their extremities and supporting said platform, the buoyant members being provided with diametrical tubular braces through which the assembling rods extend, the tubular brace members carrying terminal nuts exterior to the buoyant members and serving as spacers therebetween, the buoyant members being depressed at the points of location. of the nuts to provide clearance spaces for the latter to bring the buoyant members into close proximity laterally.
